How to create realistic splinters from wood in blender?
I have made this simple (but probably not perfect) wood splinter bending simulation with the blender fracture modifier.I used more and shorter splinters in the middle so the rubbery constraints let them atleast roughly look like bent longer splinters. 
The advantage of this being a modifier is you can just apply the mesh in the "bent" state and edit further if necessary. I also tried with a simple deform after fracture, but this did not look good at all...

The fracture modifier is a separate branch. Links to builds are here

or here (latest windows build): http://graphicall.org/1148

Will upload a blend if I can find the "BlendExchange" button again somewhere... so for now just a pasteall link...
